10 | Strange behaviour with ORDER BY and INHi, after trying out objectdb for a while now and being quite impressed by its speed and overall performance I noticed a strange behaviour where an ORDER BY - directive isn't executed as it should be (and usually is, except in this special combination-case). Ordering seems to be ignored if we order |

10 | Index causes increased memory usageHello, In an effort to increase the speed of our queries with our embedded ObjectDB system, we configured our JDO file that defines our persistable objects with some unique String indices. While this improved query performance considerably, we have noted that our database application is consuming |
